Description

L'invention concerne un ensemble porte-gant pour une enceinte de confinement, plus connue sous le nom de boîte à gants.The invention relates to a glove holder assembly for a containment enclosure, better known under the name of glove box.

Une enceinte de confinement est une chambre à parois rigides, étanches, présentant généralement une vitre transparente permettant de voir à l'intérieur de l'enceinte, depuis l'extérieur. Cette enceinte est munie de plusieurs orifices dans chacun desquels est fixé un gant. Les techniciens utilisant cette enceinte de confinement, se servent de ces gants pour travailler à l'intérieur de ladite enceinte et pour manipuler divers produits toxiques ou radioactifs. En conséquence, il est essentiel que ces enceintes soient étanches afin d'éviter toute pollution à l'extérieur. Les gants, lorsqu'ils sont usagés, doivent donc être remplacés, tout en conservant l'étanchéité de l'enceinte.A confinement enclosure is a chamber with rigid, watertight walls, generally having a transparent pane making it possible to see inside the enclosure, from the outside. This enclosure is provided with several orifices in each of which is fixed a glove. Technicians using this containment, use these gloves to work inside the containment and to handle various toxic or radioactive products. Consequently, it is essential that these enclosures are waterproof in order to avoid any pollution outside. Gloves, when worn, must therefore be replaced, while retaining the tightness of the enclosure.

Les gants classiquement utilisés sont des gants formés d'une seule pièce, d'une longueur d'environ 70 à 80 cm couvrant la main, l'avant-bras et une partie du bras de l'utilisateur. Ces gants, et notamment la partie protégeant la main, s'usent très rapidement et ont une durée de vie limitée, car ils sont utilisés en milieu nitrique et/ou radioactif.Gloves conventionally used are gloves formed in one piece, with a length of about 70 to 80 cm covering the hand, the forearm and part of the user's arm. These gloves, and in particular the part protecting the hand, wear very quickly and have a limited lifespan, because they are used in nitric and / or radioactive medium.

L'élimination de ces gants crée une quantité de déchets importante. A titre d'exemple purement illustratif, sachant qu'un gant présente une masse totale d'environ 250 g, et qu'on utilise en moyenne 500 gants par an dans une unité de production, on parvient à créer une masse de déchets d'environ 125 kg.Disposing of these gloves creates a significant amount of waste. As a purely illustrative example, knowing that a glove has a total mass of around 250 g, and that an average of 500 gloves are used per year in a production unit, we manage to create a mass of waste about 125 kg.

En outre, le remplacement de ces gants est coûteux, car il faut changer la totalité du gant, alors que seule la partie d'extrémité protégeant la main est généralement abîmée.In addition, replacing these gloves is costly, since the entire glove must be changed, while only the end part protecting the hand is generally damaged.

De plus, il pourrait être intéressant d'utiliser des gants en deux parties, avec une première partie protégeant le bras et une deuxième partie protégeant uniquement la main. Cette deuxième partie pourrait être réalisée dans des matériaux différents et présenter une épaisseur, une résistance, une forme et des dimensions différentes en fonction des applications ou des utilisateurs auxquels elle est destinée. Ainsi, l'utilisateur pourrrait travailler avec des gants de protection de la main extrêmement fins, du type gant de chirurgien pour des manipulations précises et délicates et avec des gants épais pour des manipulations nécessitant une protection particulière mais pas une grande finesse de doigté. Actuellement, ceci est difficilement mis en pratique, puisqu'il est souvent nécessaire de changer la totalité du gant, lorsqu'on souhaite remplacer celui-ci.In addition, it could be interesting to use gloves in two parts, with a first part protecting the arm and a second part protecting only the hand. This second part could be made of different materials and have a different thickness, resistance, shape and dimensions depending on the applications or users for which it is intended. Thus, the user could work with extremely fine hand protection gloves, of the surgeon's glove type for precise and delicate manipulations and with thick gloves for manipulations requiring special protection but not great finesse of fingering. Currently, this is difficult to put into practice, since it is often necessary to change the entire glove, when it is desired to replace it.

Pour résoudre ces problèmes de déchets et de remplacement de gants usagés, on connaît, d'après le brevet US-A-4 141 609, un ensemble porte-gant comprenant un manchon de protection du bras et de l'avant-bras, muni de soufflets et un gant de protection de la main, ce gant étant monté sur le manchon de protection par des moyens de fixation amovibles. Chaque gant amovible est fixé sur un rond de gant coopérant avec un anneau prévu à l'extrémité du manchon de protection à soufflets. Lors du changement du gant de protection de la main, il est nécessaire d'utiliser un outil spécial pour déverrouiller et séparer le rond de gant, de l'extrémité du manchon à soufflets, afin d'introduire un gant de remplacement muni également d'un rond de gant. Ce dispositif est complexe à mettre en oeuvre et du fait de la nécessité d'utiliser des ronds de gant, augmente la quantité de déchets. En outre, le manchon à soufflets est rigide et limite les mouvements du bras et de l'avant-bras de l'utilisateur.To solve these problems of waste and replacement of used gloves, we know, from US-A-4,141,609, a glove holder assembly comprising a sleeve for protecting the arm and forearm, provided bellows and a hand protection glove, this glove being mounted on the protective sleeve by removable fixing means. Each removable glove is fixed to a glove ring cooperating with a ring provided at the end of the protective bellows sleeve. When changing the hand protection glove, it is necessary to use a special tool to unlock and separate the glove ring from the end of the bellows sleeve, in order to introduce a replacement glove also fitted with a round of glove. This device is complex to implement and because of the need to use glove rings, increases the amount of waste. In addition, the bellows sleeve is rigid and limited the user's arm and forearm movements.

En conséquence, l'invention a pour but de remédier aux inconvénients précédemment cités.Consequently, the object of the invention is to remedy the drawbacks mentioned above.

A cet effet, l'invention concerne un ensemble porte-gant pour une enceinte de confinement, cette enceinte comportant au moins une ouverture d'accès sur laquelle est fixé un rond de gant, l'ensemble porte-gant comportant un manchon de protection du bras et de l'avant-bras fixé sur ledit rond de gant et un gant de travail protégeant la main et muni de moyens d'assemblage avec ledit manchon de protection.To this end, the invention relates to a glove holder assembly for a confinement enclosure, this enclosure comprising at least one access opening on which a glove ring is fixed, the glove holder assembly comprising a protective sleeve from the arm and forearm fixed on said glove ring and a work glove protecting the hand and provided with means of assembly with said protective sleeve.

Selon les caractéristiques de l'invention, le manchon de protection comprend au moins deux parties, une première partie munie de soufflets et une deuxième partie réalisée dans un matériau souple, cette deuxième partie pouvant se replier à l'intérieur de ladite première partie et l'ensemble porte-gant selon l'invention comprend des moyens de blocage des moyens d'assemblage du gant et du manchon de protection, ces moyens de blocage étant mobiles entre une position verrouillée dans laquelle ils maintiennent les moyens d'assemblage et le gant à l'extérieur de l'enceinte et une position déverrouillée dans laquelle ils autorisent le passage du gant et de ses moyens d'assemblage entre l'intérieur et l'extérieur de l'enceinte.According to the characteristics of the invention, the protective sleeve comprises at least two parts, a first part provided with bellows and a second part made of a flexible material, this second part being able to fold back inside said first part and l glove holder assembly according to the invention comprises means for blocking the means for assembling the glove and the protective sleeve, these blocking means being movable between a locked position in which they hold the assembly means and the glove the outside of the enclosure and an unlocked position in which they allow the glove and its assembly means to pass between the inside and the outside of the enclosure.

De façon avantageuse, les moyens d'assemblage du gant et du manchon de protection comprennent un bracelet porte-gant prévu à l'extrémité dudit manchon et apte à coopérer avec un joint torique prévu sur le gant, et les moyens de blocage comprennent au moins deux éléments pouvant être assemblées l'un avec l'autre autour du rond de gant de l'enceinte, chacun de ces éléments présentant un épaulement en arc de cercle apte à recevoir au moins une partie dudit bracelet porte-gant et à bloquer celui-ci lorsque les dits éléments sont assemblées en position verrouillée.Advantageously, the means for assembling the glove and the protective sleeve comprise a glove-carrying strap provided at the end of said sleeve and able to cooperate with an O-ring provided on the glove, and the locking means comprise at least two elements that can be assembled with each other around the glove ring of the enclosure, each of these elements having a shoulder in an arc able to receive at least part of said glove-carrying bracelet and to block the latter when said elements are assembled in the locked position.

Ainsi, ces moyens de blocage permettent de maintenir le gant à l'extérieur de l'enceinte, sans que l'utilisateur ait besoin de le tenir et sans que ce gant ne soit aspiré à l'intérieur de l'enceinte du fait de la dépression qui règne à l'intérieur de celle-ci. Le rond de gant se présente correctement face à l'utilisateur et celui-ci peut aisément adapter le deuxième gant de remplacement autour du premier.Thus, these blocking means make it possible to keep the glove outside the enclosure, without the user needing to hold it and without this glove being sucked inside the enclosure due to the depression that reigns inside of it. The glove ring is correctly facing the user and the user can easily adapt the second replacement glove around the first.

De préférence, la première partie munie de soufflets du manchon de protection assure la protection du bras et la deuxième partie de ce manchon, réalisée en matériau souple, assure la protection de l'avant-bras et du coude de l'utilisateur.Preferably, the first part provided with bellows of the protective sleeve protects the arm and the second part of this sleeve, made of flexible material, ensures the protection of the user's forearm and elbow.

Ainsi, grâce à ces caractéristiques de l'invention, les mouvements de l'utilisateur sont facilités puisqu'il peut plier le coude beaucoup plus facilement.Thus, thanks to these characteristics of the invention, the movements of the user are facilitated since he can bend the elbow much more easily.

En outre, l'ensemble porte-gant selon l'invention comprend des moyens de fermeture de la première partie du manchon permettant d'isoler cette première partie de l'intérieur de l'enceinte et de maintenir la deuxième partie du manchon à l'intérieur de la première partie.In addition, the glove holder assembly according to the invention comprises means for closing the first part of the sleeve making it possible to isolate this first part from the interior of the enclosure and to maintain the second part of the sleeve at the inside of the first part.

La deuxième partie en matériau souple peut être repliée à l'intérieur de la première partie à soufflets, ce qui n'était pas le cas dans le brevet US-A-4 141 609, du fait de la rigidité du matériau utilisé pour la réalisation de la totalité du manchon de protection. Les moyens de fermeture permettent donc lorsque l'utilisateur sort le gant de protection de la main à l'extérieur de l'enceinte, d'empêcher que la partie souple du manchon ne soit aspirée à l'intérieur de l'enceinte, du fait de la dépression qui règne à l'intérieur de celle-ci. On évite ainsi que cette partie souple n'entre accidentellement au contact d'une source de chaleur ou d'un produit agressif se trouvant à l'intérieur de l'enceinte.The second part of flexible material can be folded inside the first part with bellows, which was not the case in US-A-4 141 609, due to the rigidity of the material used for the realization of the entire protective sleeve. The closing means therefore make it possible, when the user takes the protective glove out of the hand outside the enclosure, to prevent the flexible part of the sleeve from being sucked inside the enclosure, because of the depression that reigns inside it. This prevents this flexible part from accidentally coming into contact with a heat source or an aggressive product located inside the enclosure.

De façon avantageuse, les moyens de fermeture comprennent un anneau disposé sur le manchon de protection, au niveau de la jonction entre la première partie à soufflets et la deuxième partie souple et un bouchon muni de moyens de fixation sur ledit anneau.Advantageously, the closure means comprise a ring disposed on the protective sleeve, at the junction between the first bellows part and the second flexible part and a plug provided with means for fixing to said ring.

De façon avantageuse, les moyens de fixation comprennent un taraudage et l'anneau est fileté sur sa surface externe.Advantageously, the fixing means comprise a thread and the ring is threaded on its external surface.

Grâce à cette disposition, la partie rigide à soufflets reste à l'intérieur de l'enceinte, tandis que la partie souple peut se plier facilement au niveau de la liaison avec l'anneau de fermeture, pour être amenée à l'intérieur dudit soufflet.Thanks to this arrangement, the rigid bellows part remains inside the enclosure, while the flexible part can easily bend at the connection with the closure ring, to be brought inside said bellows. .

Comme illustré en figure 1, l'ensemble porte-gant selon l'invention est destiné à équiper une enceinte de confinement 1 munie de parois 2 séparant l'extérieur 3 de l'enceinte, de l'intérieur 4. De façon classique, cette enceinte 1 comprend en outre un filtre 5, une pompe 6 assurant la dépression à l'intérieur de ladite enceinte et une boîte de transfert 7 permettant d'introduire ou de sortir des outils ou des produits de l'intérieur de l'enceinte 1. L'une des parois 2 de l'enceinte présente en outre une fenêtre transparente 8 permettant à l'utilisateur de regarder à l'intérieur de l'enceinte 1.As illustrated in FIG. 1, the glove-holder assembly according to the invention is intended to equip a confinement enclosure 1 provided with walls 2 separating the exterior 3 of the enclosure, from the interior 4. Conventionally, this enclosure 1 further comprises a filter 5, a pump 6 ensuring the vacuum inside said enclosure and a transfer box 7 making it possible to introduce or remove tools or products from inside the enclosure 1. One of the walls 2 of the enclosure also has a transparent window 8 allowing the user to look inside the enclosure 1.

Comme illustré en figure 4, la paroi 2 présente au moins une ouverture d'accès 9 (généralement il y en a deux pour les deux bras de l'utilisateur) cette ouverture étant de préférence circulaire. Un rond de gant 10 est fixé au niveau de cette ouverture 9 de la paroi. Un manchon de protection 11 du bras et de l'avant-bras ainsi qu'un gant protégeant la main sont fixés sur ce rond de gant 10 de façon amovible.As illustrated in FIG. 4, the wall 2 has at least one access opening 9 (generally there are two for the two arms of the user) this opening preferably being circular. A glove ring 10 is fixed at this opening 9 of the wall. A protective sleeve 11 of the arm and forearm as well as a glove protecting the hand are fixed on this glove ring 10 in a removable manner.

Le manchon de protection 11 comprend une première partie 12 munie de soufflets et une deuxième partie 13 réalisée dans un matériau souple. En outre, un gant de travail 15 est fixé par des moyens d'assemblage amovibles 17 sur la deuxième partie 13 du manchon de protection.The protective sleeve 11 comprises a first part 12 provided with bellows and a second part 13 made of a flexible material. In addition, a work glove 15 is fixed by removable assembly means 17 on the second part 13 of the protective sleeve.

Plus précisément, la première partie 12 munie de soufflets permet d'assurer la protection du bras, tandis que la partie souple 13 permet d'assurer la protection de l'avant-bras et du coude. Les mouvements de l'utilisateur sont ainsi facilités. Les longueurs respectives de ces deux parties 12, 13 sont conçues pour correspondre aux dimensions moyennes du bras d'un utilisateur.More specifically, the first part 12 provided with bellows ensures protection of the arm, while the flexible part 13 ensures protection of the forearm and the elbow. The movements of the user are thus facilitated. The respective lengths of these two parts 12, 13 are designed to correspond to the average dimensions of the arm of a user.

De façon avantageuse, la partie rigide munie de soufflets 12 est réalisée en caoutchouc synthétique semi rigide, et la partie souple 13 est réalisée en vinyle. Toutefois, on peut choisir d'autres matériaux dès lors qu'ils répondent aux critères de rigidité ou de souplesse exigés et qu'ils présentent une résistance à l'oxydation et/ou aux phénomènes de radiolyse, et/ou aux acides forts.Advantageously, the rigid part provided with bellows 12 is made of semi-rigid synthetic rubber, and the flexible part 13 is made of vinyl. However, other materials can be chosen as soon as they meet the criteria of rigidity or flexibility required and they exhibit resistance to oxidation and / or to radiolysis phenomena, and / or to strong acids.

Les moyens d'assemblage 17 du gant 15 et du manchon 11 comprennent un bracelet porte-gant fixé à l'extrémité de la partie souple 13 du manchon et apte à recevoir ledit gant 15. Ce bracelet porte-gant 17 est constitué par un anneau ou portion de tube cylindrique, présentant sur sa surface extérieure deux gorges annulaires sensiblement parallèles référencées 19 et 21, la gorge 19 se trouvant sensiblement au centre de ce bracelet. Ces gorges 19, 21 permettent de recevoir un joint torique 22 solidaire de l'extrémité du gant 15. En outre, ce bracelet porte-gant 17 présente à son extrémité opposée à celle présentant la gorge 21 une partie tronconique 23 sur laquelle est fixé l'extrémité de la partie 13 du manchon. Cette fixation peut se faire par collage ou thermosoudage. Cette fixation est telle que le bracelet porte-gant 17 se trouve à l'intérieur de la partie souple 13 du manchon.The assembly means 17 of the glove 15 and the sleeve 11 comprise a glove-carrying strap fixed to the end of the flexible part 13 of the sleeve and capable of receiving said glove 15. This glove-carrying strap 17 consists of a ring or portion of cylindrical tube, having on its outer surface two substantially parallel annular grooves referenced 19 and 21, the groove 19 being located substantially in the center of this bracelet. These grooves 19, 21 make it possible to receive an O-ring 22 integral with the end of the glove 15. In addition, this glove-carrying bracelet 17 has at its end opposite to that having the groove 21 a frustoconical part 23 on which is fixed the end of the part 13 of the sleeve. This fixing can be done by gluing or heat sealing. This attachment is such that the glove strap 17 is located inside the flexible part 13 of the sleeve.

Le rond de gant 10 a également une forme tubulaire cylindrique. Il présente une nervure 25 annulaire périphérique définie par deux rebords annulaires 27 et 29. Le rebord 27 est placé à l'intérieur 4 de l'enceinte de confinement 1, tandis que le rebord 29 est placé à l'extérieur 3 de l'enceinte. La nervure 25 est conçue pour recevoir les bords de la paroi 2 formant l'ouverture 9. Ce rond de gant 10 présente en outre une aile latérale 31 s'étendant vers l'extérieur de l'enceinte perpendiculairement à la paroi 2. Cette aile latérale 31 annulaire présente en outre sur sa périphérie extérieure deux gorges également annulaires référencées respectivement 33 et 35. La gorge 33 est située entre la gorge 35 et la nervure 25. La gorge 35 est destinée à recevoir le joint torique 37 formant l'extrémité du manchon à soufflets 12 et assure ainsi la fixation amovible de ce manchon.The glove ring 10 also has a cylindrical tubular shape. It has a peripheral annular rib 25 defined by two annular flanges 27 and 29. The flange 27 is placed inside 4 of the confinement enclosure 1, while the flange 29 is placed outside 3 of the enclosure. The rib 25 is designed to receive the edges of the wall 2 forming the opening 9. This glove ring 10 also has a lateral wing 31 extending towards the outside of the enclosure perpendicular to the wall 2. This wing lateral annular 31 further has on its outer periphery two also annular grooves referenced respectively 33 and 35. The groove 33 is located between the groove 35 and the rib 25. The groove 35 is intended to receive the O-ring 37 forming the end of the bellows sleeve 12 and thus ensures the removable fixing of this sleeve.

Des moyens de fermeture 39 de la première partie 12 du manchon sont prévus et disposés à la jonction entre les deux parties 12 et 13 du manchon de protection. Plus précisément, ces moyens de fermeture 39 comprennent un anneau fileté sur sa surface extérieure et fixé par collage ou thermosoudage respectivement à l'extrémité libre du manchon à soufflets 12 et à l'extrémité libre de la partie souple 13. Le filetage est référencé 40. Cet anneau 39 est apte à coopérer avec un bouchon de fermeture 41 représenté à la figure 7 et qui va maintenant être décrit plus en détail. Ce bouchon 41 est constitué par un disque ou fond 42 en matière plastique muni d'un rebord annulaire périphérique 43 taraudé de façon à pouvoir être vissé sur le filtage 40 de l'anneau 39. Le taraudage du bouchon 41 constitue un exemple de moyens de fixation sur l'anneau 39. Toutefois, il est bien évident que l'on pourrait prévoir d'autre modes de fixation tels qu'une fixation à baïonnette, un cran ou l'assemblage en force, sans pour autant sortir du cadre de l'invention. En outre, ce bouchon de fermeture 41 comprend sensiblement en son centre une grille d'aération 45. Il comprend également une poignée de préhension 47 fixée sur le fond 42 du bouchon de part et d'autre de la grille 45. Cette grille 45, lorsque le bouchon 41 est en place sur l'anneau 39, permet d'assurer la dépression à l'intérieur du soufflet 12.Closing means 39 of the first part 12 of the sleeve are provided and arranged at the junction between the two parts 12 and 13 of the protective sleeve. More specifically, these closing means 39 comprise a threaded ring on its outer surface and fixed by gluing or heat-sealing respectively to the free end of the bellows sleeve 12 and to the free end of the flexible part 13. The thread is referenced 40 This ring 39 is able to cooperate with a closure plug 41 shown in FIG. 7 and which will now be described in more detail. This plug 41 is constituted by a plastic disc or bottom 42 provided with a peripheral annular rim 43 tapped so as to be able to be screwed onto the thread 40 of the ring 39. The tapping of the plug 41 constitutes an example of means of attachment to the ring 39. However, it is obvious that one could provide other methods of attachment such as a bayonet attachment, a notch or assembly in force, without departing from the scope of the 'invention. In addition, this closure cap 41 substantially comprises in its center an air grille 45. It also comprises a grip 47 attached to the bottom 42 of the plug on either side of the grid 45. This grid 45, when the plug 41 is in place on the ring 39, ensures the vacuum inside the bellows 12.

L'ensemble porte-gant selon l'invention comprend également des moyens de blocage des moyens d'assemblage 17 du gant 15 et du manchon 11. Ces moyens de blocage sont illustrés notamment en figures 5 et 6 et portent la référence générale 49. Ces moyens de blocage 49 comprennent de préférence, deux éléments symétriques et sensiblement identiques. On pourrait toutefois prévoir plus de deux éléments. L'élément supérieur (par rapport à la figure 6 et par rapport au sens normal d'utilisation), porte la référence 51 et l'élément inférieur porte la référence 53. Les moyens de blocage 49 sont conçus pour être disposés sur l'aile latérale 31 du rond de gant 10 et pour recouvrir celui-ci. Plus précisement, chaque élément 51, 53 présente la forme d'une gouttière cintrée en demi cercle avec une coupe sensiblement en C comme cela apparaît mieux en figure 5. Chaque gouttière est disposée "à cheval" sur au moins une partie de l'aile latérale 31 du rond du gant. Chaque élément 51, 53 comprend donc un bord périphérique latéral 55 terminé par un élément formant joint d'étanchéité 57 destiné à s'engager dans la gorge 33 du rond de gant 10. Ce rebord 55 se prolonge vers son centre par une face avant 59, et par une partie 63 légèrement oblique. Cette partie oblique 63 se prolonge intérieurement par un épaulement en arc de cercle 65 destiné à recevoir la partie tronconique 23 du bracelet porte-gant 17. En outre, ces deux éléments 51, 53 présentent intérieurement, au niveau de leur ouverture centrale 67, quatre bavettes anti-retour 69 réalisées en matière plastique souple et épaisse (voir figure 6). Ces bavettes anti-retour 69 ont pour rôle d'empêcher que le gant 15 ne soit aspiré à l'intérieur de la partie de protection en soufflets 12.The glove holder assembly according to the invention also comprises means for blocking the assembly means 17 of the glove 15 and the sleeve 11. These blocking means are illustrated in particular in FIGS. 5 and 6 and bear the general reference 49. These locking means 49 preferably comprise two symmetrical and substantially identical elements. However, there could be more than two elements. The upper element (relative to FIG. 6 and relative to the normal direction of use), bears the reference 51 and the lower element bears the reference 53. The locking means 49 are designed to be arranged on the wing side 31 of the glove ring 10 and to cover it. More precisely, each element 51, 53 has the shape of a gutter bent in a semicircle with a substantially C-shaped cut as it appears better in FIG. 5. Each gutter is arranged "astride" on at least part of the wing lateral 31 of the glove circle. Each element 51, 53 therefore comprises a lateral peripheral edge 55 terminated by an element forming a seal 57 intended to engage in the groove 33 of the glove ring 10. This flange 55 is extended towards its center by a front face 59 , and by a slightly oblique part 63. This oblique part 63 is internally extended by a shoulder in an arc of a circle 65 intended to receive the frustoconical part 23 of the glove-carrying bracelet 17. In addition, these two elements 51, 53 have internally, at their central opening 67, four non-return flaps 69 made of flexible plastic and thick (see Figure 6). The role of these non-return flaps 69 is to prevent the glove 15 from being sucked inside the protective portion in bellows 12.

Les moyens de blocage 49 peuvent occuper deux positions, une première position verrouillée dans laquelle les deux éléments 51 et 53 sont verrouillées par des moyens 71 et une seconde position déverrouillée, dans laquelle ces deux éléments sont écartés l'un de l'autre et permettent le passage du rond de gant 17 et du gant 15.The locking means 49 can occupy two positions, a first locked position in which the two elements 51 and 53 are locked by means 71 and a second unlocked position, in which these two elements are separated from one another and allow the passage of the glove ring 17 and the glove 15.

Les moyens de verrouillage 71 sont constitués par deux crochets à ressort prévu de part et d'autre des deux éléments 51 et 53. En position verrouillée, les deux éléments 51 et 53 sont plaqués l'un conte l'autre (partie gauche de la figure 6) et en position déverrouillée, l'élément inférieur 53 est légèrement écarté de l'élément supérieur 51 (partie droite de la figure 6).The locking means 71 consist of two spring hooks provided on either side of the two elements 51 and 53. In the locked position, the two elements 51 and 53 are pressed one against the other (left part of the Figure 6) and in the unlocked position, the lower element 53 is slightly separated from the upper element 51 (right part of Figure 6).

Le fonctionnement de ce dispositif va maintenant être expliqué plus en détail en faisant référence aux figures 2 et 3.The operation of this device will now be explained in more detail with reference to Figures 2 and 3.

La partie A de la figure 2 illustre l'ensemble porte-gant au repos, c'est-à-dire quand la main et le bras de l'utilisateur ne sont pas à l'intérieur. On notera que les moyens de blocage 49 n'ont été que partiellement représentés.Part A of Figure 2 illustrates the glove holder assembly at rest, that is to say when the user's hand and arm are not inside. Note that the locking means 49 have only been partially shown.

Lorsque l'utilisateur souhaite changer le gant 15 dont le joint torique 22 est positionné dans la gorge annulaire 21, il introduit sa main et son bras à l'intérieur de l'ensemble porte-gant comme représenté dans la partie B de la figure 2, et il saisit le bouchon de fermeture 41 par l'intermédiaire de sa poignée de préhension 47. Il recule la main et le bras à l'intérieur du manchon de protection 11 jusqu'à amener le bouchon 41 au niveau de l'anneau 39 et visse alors le bouchon sur cet anneau par rotation d'un quart de tour. Il se retrouve alors dans la situation illustrée dans la partie C de la figure 2). Ensuite, il continue à retirer sa main ainsi que le gant 15 jusqu'à amener celui-ci à l'extérieur de l'enceinte, et à retourner le gant 15 comme cela est illustré dans la partie D de la figure 3. Pour ce faire, il est nécessaire évidemment que le dispositif de blocage 49 soit déverrouillé (position basse de l'élément 53 illustrée en partie C de la figure 2). Ensuite, de son autre main, il verrouille le dispositif de blocage 49 et l'anneau 17 repose donc sur l'épaulement 65 du dispositif 49. Il peut alors enfiler par dessus le gant usagé 15 qui se trouve à l'envers, un nouveau gant 15', disposé également à l'envers et dont le joint torique 22' est positionné dans la gorge annulaire 19, (partie D de la figure 3).When the user wishes to change the glove 15 whose O-ring 22 is positioned in the annular groove 21, he introduces his hand and his arm inside the glove-holder assembly as shown in part B of FIG. 2 , and he grasps the closure cap 41 by means of its grip handle 47. He moves his hand and arm back inside the protective sleeve 11 until bringing the plug 41 at the level of the ring 39 and then screws the plug onto this ring by rotating a quarter of a turn. It then finds itself in the situation illustrated in part C of FIG. 2). Then, he continues to withdraw his hand as well as the glove 15 until bringing the latter outside the enclosure, and to turn over the glove 15 as illustrated in part D of FIG. 3. For this do, it is obviously necessary that the locking device 49 is unlocked (low position of the element 53 illustrated in part C of Figure 2). Then, with his other hand, he locks the locking device 49 and the ring 17 therefore rests on the shoulder 65 of the device 49. He can then put on the used glove 15 which is upside down, a new glove 15 ', also arranged upside down and whose O-ring 22' is positioned in the annular groove 19, (part D of FIG. 3).

Ensuite, il enfonce sa main dans le gant neuf 15' pour saisir le gant usagé 15, sortir le joint torique 22 du gant usagé 15 de la gorge annulaire 21 et faire tomber le gant usagé 15 à l'intérieur de l'ensemble porte-gant.Then, he pushes his hand into the new glove 15 'to grasp the used glove 15, remove the O-ring 22 from the used glove 15 from the annular groove 21 and drop the used glove 15 inside the holder assembly. glove.

Le joint torique 22' du nouveau gant 15' est alors déplacé de la gorge annulaire 19 dans la gorge annulaire 21 tout en gardant le maximum de contact avec le bracelet porte-gant 17.The O-ring 22 ′ of the new glove 15 ′ is then moved from the annular groove 19 into the annular groove 21 while keeping the maximum contact with the glove strap 17.

Pour une étanchéité et une sécurité maximales, on applique au moins un tour de ruban adhésif (non représenté) au niveau de la gorge annulaire 21 dans laquelle est placé le joint torique 22'.For maximum sealing and security, at least one turn of adhesive tape (not shown) is applied at the level of the annular groove 21 in which the O-ring 22 'is placed.

Ensuite, comme illustré dans la partie E de la figure 3, il enfonce de nouveau sa main à l'intérieur du gant 15' de façon à le remettre à l'endroit, à l'intérieur du soufflet 11.Then, as illustrated in part E of FIG. 3, he pushes his hand again inside the glove 15 'so as to put it back in place, inside the bellows 11.

Il peut ensuite déverrouiller le bouchon 41 par rotation de celui-ci et le poser à l'intérieur de l'enceinte. Il se trouve alors dans la situation représentée dans la partie F de la figure 3 où sa main est protégée par le gant 15'.He can then unlock the plug 41 by rotation of the latter and place it inside the enclosure. He is then in the situation shown in part F of FIG. 3 where his hand is protected by the glove 15 '.
